ABB Inora 2 Gang 2 Way 20AX Switch Starry Black BL115-885

Two gang means the switch has two separately operated controls on one faceplate. Two way means each control can be wired with another two-way switch so that the same lighting circuit is controlled from two locations. The 20AX marking is a switch rating intended to account for lighting loads that may produce higher switching currents, including certain fluorescent or inductive lighting circuits. It must not be interpreted as permission to exceed the connected load, cable or protective-device rating.

This switch is suitable for indoor lighting controls in UAE villas, apartments, offices, hotels, retail units and other construction projects. Typical applications include controlling two separate lighting zones from one point or providing two-location control in corridors, staircases, bedrooms and rooms with more than one entrance. Confirm the environmental conditions and circuit design before using it in kitchens, bathrooms, outdoor areas or other locations exposed to moisture, dust or heat.

In a two-way circuit, one gang is connected to another compatible two-way switch using a common conductor and two traveller or strapper conductors. Operating either switch changes the circuit path and turns the connected light on or off. Because this model has two gangs, it can support two independent two-way lighting circuits when the correct cables, matching switches and suitable back boxes are provided.

A two-way switch can generally be configured for one-way operation by using the common terminal and the appropriate switched terminal, leaving the unused terminal unconnected. Terminal identification and the manufacturer's wiring information must be followed. Installation should be completed and tested by a qualified electrician rather than relying on wire colour alone.

It may be used to switch compatible LED lighting circuits, provided the total load and the LED driver's inrush current remain within the switch manufacturer's limits. LED drivers can create a brief startup current substantially higher than their normal operating current, especially when several fittings are connected together. For large LED circuits, an electrician should verify the driver data and consider a contactor or relay if direct switching is unsuitable.

Isolate the circuit at the distribution board, lock out the supply where practicable and prove the conductors are dead with an approved tester. Mount a compatible electrical back box, prepare and identify the conductors, and terminate them according to ABB's terminal markings and the approved circuit diagram. Tighten terminals to the manufacturer's specified torque, arrange cables without damaging insulation, secure and align the switch plate, then perform continuity, insulation-resistance, polarity and functional tests before energising the circuit. Installation must be carried out by a qualified electrician.

Check the model number BL115-885, required number of gangs, one-way or two-way circuit arrangement, connected lighting load, LED-driver inrush current, conductor size, earthing provisions and back-box compatibility. Also verify the required faceplate finish, installation depth and whether matching Inora accessories are needed across the project. For substitutions in an existing installation, compare the wiring arrangement and mounting system rather than selecting by appearance alone.

Yes. Two-gang and two-way lighting controls are commonly specified in UAE residential, commercial and hospitality projects, particularly for staircases, corridors, bedrooms and multi-entrance rooms. The Starry Black finish suits contemporary interiors and coordinated dark electrical accessories. Final selection and installation should comply with the project's approved specifications, applicable UAE electrical requirements and the rules of the relevant authority, such as DEWA or the applicable emirate utility.

This product is primarily described as a lighting switch, and its 20AX marking should not automatically be treated as a general appliance or motor-control rating. Fans, pumps, motors and other inductive equipment may have high starting currents and may require a dedicated isolator, fan controller, relay or contactor. Socket outlets must use correctly rated socket accessories and appropriate circuit protection. An electrical engineer or qualified electrician should confirm suitability for any non-lighting load.

Cable type and conductor size must be selected from the approved electrical design based on circuit load, protective device, installation method, voltage drop and local requirements. Two-way circuits require additional traveller conductors between switching points, and a two-gang installation may need more wiring space than a basic one-way switch. Use a back box that matches the ABB Inora accessory's mounting arrangement and provides sufficient depth for safe terminations; verify exact compatibility from the current ABB technical documentation before purchase.

Switch off and isolate the circuit before inspection or maintenance. Clean the visible surface with a soft, dry or slightly damp cloth, and avoid abrasive pads, solvents, bleach or strong chemical cleaners that could damage the Starry Black finish. Do not allow water to enter the mechanism. Replace the switch and have the circuit inspected if there is cracking, discoloration, overheating, arcing, looseness or unreliable operation.
